jsonArray转jsonObject

JSONArrayjsonarray= JSONArray.fromObject(actinfo);

              for(inti= 0;i<jsonarray.size();i++) {

                   JSONObjectob  = (JSONObject)jsonarray.get(i);

                   

                   activityimg= ob.get("activityimg").toString();

                   activityno=ob.get("activityno").toString();

                   

                   beans.setActivityimg(activityimg);

                   beans.setActivityno(activityno);

                   beans.setActivityid(bean.getId().toString());

              }

通过循环迭代就可以取出每个jsonarray的值转换成jsonobject
